1. What is Percentage Increase?

Percentage increase measures how much a quantity has grown relative to its original value, expressed as a percentage. It's commonly used in finance, economics, statistics, and many other fields.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Value — The current or final value
• Old Value — The original or initial value

Explanation: The formula calculates the difference between the new and old values, divides by the old value to get the relative change, then multiplies by 100 to convert to a percentage.

3. Importance of Percentage Increase Calculation

Details: Percentage increase is crucial for understanding growth rates, comparing changes between different scales, and making data-driven decisions in business and research.

4. Using the Calculator

Tips: Enter both old and new values. The old value cannot be zero (division by zero is undefined). Values can be positive or negative, but the interpretation differs.

5. Frequently Asked Questions (FAQ)

Q1: What if the old value is zero?
A: Percentage increase is undefined when the old value is zero, as you cannot divide by zero. In such cases, absolute change might be more appropriate.

Q2: Can percentage increase be negative?
A: Yes, if the new value is less than the old value, the result will be negative, indicating a percentage decrease.

Q3: How is this different from percentage points?
A: Percentage increase is relative to the original value, while percentage points measure absolute difference between percentages.

Q4: When is percentage increase most useful?
A: When comparing growth rates across different scales or when the relative change is more important than the absolute change.

Q5: How to interpret a 100% increase?
A: A 100% increase means the value has doubled (become twice as large as the original).
